specific Embodiment approach

[0094] In one embodiment of the present invention, since the seal to be identified in the target image is red, in order to be able to segment the seal to be identified later, all red regions in the target image are first extracted, and the specific implementation of step 101 methods, which may include:

[0095] Converting the target image from RGB color space to HSV color space;

[0096] For each pixel in the target image, determine the H value, S value and V value corresponding to the current pixel; determine whether the H value corresponding to the current pixel is in (0,8)∪(156 , 180), whether the S value is in the range of (43, 255) and whether the V value is in the range of (43, 255); if both are judged to be yes, then the current pixel set to a white pixel; otherwise, set the current pixel to a black pixel;

[0097] Each of the white pixels and each of the black pixels form the first image. There may only be a red seal to be identified in some target images, and there...

Abstract

The present invention provides a seal identification method and device, the method may include: extracting the red area in the target image to form a first image; segmenting a second image including a seal to be identified from the first image; according to the The seal to be identified is identified by using the second image and a preset standard seal image, wherein the seal to be identified corresponds to the image of the standard seal. This scheme can automatically identify the seal.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a seal identification method and device. Background technique [0002] With the continuous deepening of "Internet + government services" and "Internet + administrative examination and approval", focusing on the construction requirements of "one account, one window and one network", accelerating the construction of a "smart examination and approval" government service platform can minimize various The duplication of workload in filling in materials and reviewing makes it easier and faster for the masses to handle affairs. When reviewing various materials, in order to identify the authenticity of the materials, the identification of seals is essential. [0003] At present, it is mainly to identify the seal in the material manually. However, due to the large number of materials that need to be identified, there are also many seals that need to be identified. If you still rely on...
